ABSTRACT:
A method of manufacture of an annular seal element comprises the steps of providing an apertured backing ring with closely packed bristles extending radially outwardly from the circumference thereof, clamping the free ends of the bristle between a pair of co-axial rings and welding the rings and the outermost tips of the bristles into a unitary structure and subsequently machining away the original backing ring to leave the rings with radially inwardly extending bristles.
The invention also includes a sealing element made by the method.
